Description

[Detailed description of the invention] <Industrial field of application> This invention is a wick up-and-down device for oil-burning appliances in which the wick is connected to a wick holder via a hook fixed to the outer wall of the wick and is moved up and down. Regarding.

<Prior Art> Conventionally, in this type of lead up/down device, as disclosed in Japanese Utility Model Publication No. 39-8564, for example,
The wick and the wick holder were connected by inserting a plurality of pin-shaped hooks provided on the outer wall of the wick into hook holes in the wick holder.

<Problems to be solved by the invention> However, in this conventional type, the attachment surface of the hook to the wick is small, and the connection between the wick holder and the hook is done via a pin, and this contact surface is small, so the hook is It is easily displaced and the protruding dimensions of the wick are out of order.Furthermore, the wick is pushed by the hook and protrudes inward, causing the problem that the wick gets caught during vertical movement and prevents smooth vertical movement. Furthermore, the pin hook requires the work of caulking the pin to the core attachment plate, making it cumbersome to manufacture and also expensive.

<Means for solving the problem> This invention focuses on this point, and in order to solve the above-mentioned drawback, the structure is particularly improved by interposing the wick 1 between the wick guide pipe 2 and the wick holder 3, and further The wick 1 and the wick holder 3 are connected by fitting a plurality of hooks 4 attached to the outer wall of the wick 1 into hook holes 8 formed in the peripheral wall of the wick holder 3. Reference numeral 4 has a substantially U-shaped cross section, so that the upper and lower ends thereof protrude outward to form protruding pieces 9, and the protruding pieces 9 are formed in an arcuate shape bulging outward.

<Operation> The wick 1 is attached to the wick holder 3 by fitting a plurality of hooks 4 fixed to the outer wall of the wick 1 into the hook holes 8 formed in the peripheral wall of the wick holder 3. The hook 4 is formed into a substantially U-shaped cross section, and the contact with the lead holder 3 is made by two protruding pieces 9 whose upper and lower ends protrude outward. There is no need to worry about the projecting dimensions going out of order, and smooth vertical movement is possible at all times.Furthermore, since the protruding piece 9 has an outwardly bulging arc shape, the hook 4 can be attached to the wick 1 with some twist. can be easily fitted into the hook hole 8 of the lead holder 3, the installation dimensions can be easily managed, and there are no problems caused by using the U-shaped hook 4.

<Embodiment> Next, a wick up-and-down device for an oil-burning appliance according to this invention will be described with reference to a preferred embodiment shown in the drawings.

Reference numeral 1 denotes a fuel wick held between a wick guide pipe 2 and a wick holder 3, and three hooks 4 having a substantially U-shaped cross section are provided at equal intervals on the outer circumferential wall for connection to the wick holder 3. Stop and prepare.

The lead holder 3 includes an engaging portion 7 on one side wall that engages with an engaging pin 6 of the lead lifting arm 5, and
A hook 4 provided on the outer peripheral wall of the fuel wick 1 is provided on the peripheral wall.
Three hook holes 8 are formed, each of which has a width slightly larger than that of the hook 4.

Furthermore, since the hook 4 is formed to have a substantially U-shaped cross-section, the upper and lower ends thereof protrude outward to form protrusions 9, and the protrusions 9 are formed in the shape of an arc bulging outward. Even if the hook 4 is slightly twisted when attached, this error is absorbed so that the hook 4 can be easily inserted into the hook hole 8.

Reference numeral 10 denotes a rotating shaft connected at one end to the core lifting arm 5 and having an operating lever 11 fixed to the other end.

Next, the operation of this embodiment will be explained.

If the operating lever 11 is now operated to rotate the rotating shaft 10, the core lifting arm 5 will rotate about the rotating shaft 10 as a fulcrum in conjunction with the rotating shaft 10, and engage with the engagement pin 6. By moving up and down the wick holder 3 connected by engagement with the joint 7, the wick 1 integrated with the wick holder 3 is moved up and down along the wick guide pipe 2. Refueling wick 1 and wick holder 3
are connected via a hook 4 having a U-shaped cross section, and the hook 4 has two projecting pieces 9 whose upper and lower ends protrude outward.
Since the hook 4 is in contact with the wick holder 3 by the wick 4, the hook 4 is strong without being displaced, and the vertical movement of the wick holder 3 is reliably transmitted to the wick 1, allowing smooth vertical movement at all times. .

Also, even if the hook 4 is attached to the wick 1 with some twist, the hook 4 will not be twisted as shown in FIG.
The projecting piece 9 is formed in an arc shape toward the outside, absorbs the installation error caused by this twisting, and is easily inserted into the hook hole 8. Even if the installation dimensions of the hook 4 vary, the installation can be performed. This makes management easier. Further, the hook 4 can be manufactured by punching with a press and then bending, and is suitable for mass production and can be easily manufactured and provided at low cost.

<Effects of the invention> In short, this invention connects the wick 1 to the wick guide pipe 2.
and the wick holder 3, and the wick 1 and the wick holder 3 have a plurality of hooks 4 attached to the outer wall of the wick 1 inserted into hook holes 8 formed in the peripheral wall of the wick holder 3. In the case where the hooks 4 are formed in a substantially U-shaped cross section, the upper and lower ends thereof are protruded outward to form protruding pieces 9, and the protruding pieces 9 are expanded outward. Because it is formed into a protruding circular arc, the hook is strong and does not easily displace, and the wick can always be moved up and down smoothly without the wick's protruding dimensions going out of order. It is possible to provide a lead up/down device which can be easily used, has an extremely simple structure, can absorb variations in hook mounting dimensions, can easily manage dimensions, and can be assembled easily and at low cost.

Claims (1)

[Scope of utility model registration request] A fuel wick 1 is interposed between a wick guide pipe 2 and a wick holder 3, and a plurality of hooks 4 attached to the outer wall of the wick 1 are connected to the peripheral wall of the wick holder 3. In the case where the hooks 4 are connected by being inserted into the formed hook holes 8, the hooks 4 have a substantially U-shaped cross section, so the upper and lower ends protrude outward to form protrusions 9, and the protrusions 9 is a wick up-and-down device for oil-burning appliances, which is characterized by being formed in an arc shape that bulges outward.
